@WTE snr To all whom it concern;

Be it known that I, Fnnnnnron A.. STE# ing at Providence, in the county of'Provi- '5 dence and State of Rhode Island, have in-` tance; to minimize the use o form a part of this speciiication, Figures 1,

vented certain nerrl and useful Improve# ments in Spectacles, ofwhich the followingL is a specification. l

My invention relates tospeotacles and has for its essentiel objects,V protection against dust, dirt and Wind.; 'to atl'ord substitution of focal or other lenses to correct any visuel defect Without thev necessity of regrinding; to maintain the lenses in denite original position which is essential incaseof such. ,visnal defects as astigmatism; to render the connection between the shield and lenses inconspicuousg'to locate the shield as closely to the nose as possible; to afford an inconspicuous rest upon the nose; to permit uni-4 versal adjustment of "the spectacles relatively to the face or to the upillary dis-v tpsolder in thet construction of the parts; andA to render thel pensive.

To the above ends myinvention 'oonsists in suoli parts and combinations of parts ns1 fall Within the scope of the appended claims.`

The plates A are each inclosedfin a grooved rim'i of usual construction provided lat their outer joints with the usual leers b' in which ere pivoted the temples b2.; A portion of the rim B nearly opposite the rim joint as at 3 is straight.

opening a, against the frontface of the shield A., is located a removable rim C provided with an internal annular groove c, and having at intervals along its rear edge lateral bendable bentover the margin of the opening and against the rear face of the plate A, thus firmly holding the rim in position. At the contiguous ends of each' rim C, are perforated lugs @2, connected by a screw (-3 which ,register .in the cavity a and are thus corn cealed from View from the fre-*1t and assist in preventing sny aeeidentel annular movement of the rim.

Esch rino C lies leffeted in the groove e lens D which is inserted int-o the rim before the latter is mounted in the shield A. The

A nose res'ts provided comprising a vertical rod F having at its` lower portion va substantially horizontal forwardly lextending loop f, and extending thence rearwardly and upwardly forming an arm f to whose end is fixed an arched nose rest Gf. '.The vrod F is inserted into the groove e 'whose u per end is closed by the loop e?. which comp etes the substantial tube formed by the grooves4 e. After the rod F and the portions bf" of the rims have beenassembled in their respectivegrooves as above/described the opposite portions of the blank E are by proper tools swaged down into tubes. The loop f and the ,arm f. afford means for universal adjustment of the spectacles toward and away from the planes of the lenses, up and down, right and left, and otherwiseyand the nose rest G lis concealed by the shield. In this instance the connection of the shields to each other is strengthened by a brace H fixed at its ends to the top of the rim B.
